  The perigee contacts were nominal for CMD and TLM. The inertial maneuver was successful. This perigee we increased the sample rate for 2 telemetry packets to collect thermal data during the eclipse. The SSR was dumped prior to and post eclipse. The Orbit 512 Bus and Instrument ATS's were uplinked. We started the Hi background test.
